Lateral Expansion Joints  Manufacturers, Traders, Suppliers

A lateral expansion joint works in the same way as a hinged expansion joint does. It utilizes the ability of a bellow to rotate in angular direction. The lateral movement capability is the result of the angular rotation of the bellows and their center to center distance. The longer distance between the bellowa, the larger is the movement.
A longer center to center distance also results in lower displacement forces of the expansion joint. Lateral expansion joints are independent expansion systems in contrast to single hinged expansion joints. They are practically a two pin system. Lateral expansion joints are usually installed with a 50% pre-stressing. This is accomplished by pre-stressing the entire pipe system after the expansion joint is installed. The pre-stressing amount can be determined from the prestressing diagram in the section "assembly instructions" taking into account the installation temperature.

Lateral expansion joints, equipped with ball joints, can move in all directions within one plane. They are used for simultaneous or staggered movements from two directions. The application of this expansion joint always requires a change in direction of the piping.
